I would never buy a house ...
With a front garden that's smaller than the lounge. (And is 6-8 feet away from the public footpath and has people gawping in!)
With no driveway. (I prefer a garage too but that's not a dealbreaker.) Preferably a 2 car driveway. (Minimum!)
With homes opposite that have no driveway (as I will have to constantly tolerate people parking on the road opposite my drive.)
Without at least one lawn. (I hate gravelled or paved gardens, and ditto to hating artifical grass!)
With an open plan design. (Never liked this!)
Without drainage and sewage facilities (I do NOT want a septic tank.)
Without gas plumbed in. (I don't want to be constantly having to buy Calor gas cannisters.)
With electric-only heating.
Also, I would never buy a house that is 3 feet away from the houses either side (like with some post 1990 newbuilds.)
I'm sure there's more! 😆
